Abstract
Apparatus and methods are provided for use in sealing a vascular puncture site. The invention includes an introducer sheath with an integrated closure component. The closure component includes a fastener and an advanceable, deformable clip having a delivery configuration in which opposing sides do not contact one another, and a deployed configuration, in which the fastener causes opposing sides of the deformable clip to close towards one another. The clip is advanced along the sheath until it pierces opposing sides of a vessel wall at a puncture site. The clip is then deformed with the fastener to draw opposing sides of the puncture together, and the sheath is withdrawn to seal the wound. The clip and fastener preferably are bioabsorbable.
